Dead Down Wind here also... use their laundry soap mixed with 20 Mule Team Borax; and field spray. I don't go overboard - because you still have to watch the wind. (That's why I put a 12-18" piece of thread tied onto the front of my stabilizer).
Scent blocker silver shield. There was a sale going on at ****s. Got two gallon jugs of field spray for $9.99 each.
